> After upgrading to Hive 3.1 from Hive 1.2, I can't run my queries anymore. It seems that "if not exists" is ignored in "create view".
> *Example:*
>  # create view if not exists test as select 1;
>  # create view if not exists test as select 1;
> The second call fails with "Table already exists: default.test". I changed this to "create or replace view" as a workaround.
> Also documented [link here|https://community.hortonworks.com/questions/214772/hdp-3-hive-create-view-if-not-exists-fails.html|]
